A few days ago, some media exposed the photos of Apple launching the prototype of the early iPhone in 2007, and introduced the internal structure of the device in detail. In the two and a half years since the first launch of douwan in 2007, apple secretly developed the early iPhone. What happened to the original iPhone? Steve Jobs built the original iPhone.
This picture is an engineering verification test (EVT) sample, mainly for iPhone software and wireless technology work, such as porting Darwi from Mac OS X, reproduced from webmaster's n kernel, the verge, an American technology media website, said, Those people won't be aware of the final form of the product, and it's said that some versions of the circuit board don't have screens to reprint from the webmaster's home screen and need external components or RCA displays. Reprinted from the webmaster's home, webmaster's home, Dou play network reprinted from the webmaster's home.
Many of the components on the circuit board represent the components that will eventually enter the final product, such as 30 pin connector, SIM card slot, Wi Fi and Bluetooth antenna, including RJ11 telephone jack used to transfer the test voice call of self play network, and two mini USB connections used to access the processor and baseband chip.
The application processor is Samsung k4x1g153pc, which combines Samsung memory and arm1176jzf to run iPhone OS. In addition, there is 4G Samsung NAND storage, so you can test the software changes through the exchange card.
Although the home / menu button is actually located on the left side of the display, and the power and volume buttons are also on the circuit board, engineers can gain more in-depth command access during the development of the iPhone in 2006 and 2007.
An unusual idea is that if a circuit board is connected to a modern computer, it will be detected as an iPhone that needs to be restored by iTunes.
Apple finally launched its first iPhone on June 29, 2007. For many Apple employees, the first iPhone is just a computing device code named M68 and purple2.
